UNITED STATES PAUL TOTEMS, OF NEW HAVEN, MICHIGAN.

MUD-LUG- FOR WHEELS OF TRACTION-ENGINES.

Specification of Letters Patent.

Patented July 16, 1907.

Application filed January 21,1907. Serial No. 353.227.

To all whom it. may concern:

Be it known that I, PAUL To'rEMs, a citizen of the United States, residing at New Haven, in the county of Sh iawassee and the State of Michigan, have invented a new and useful Mud-Lug for the Wheel of a Traction- Engine, of which the following is a specification.

My invention relates to an improved mud lug, for the driving wheel of a traction engine", and the objects of my improvement, are, first, to provide-a device attachable to any traction-engine driving wheel of any make or size. except those which have a differential gear in the hub; second, to provide a device in which eight lugs can be adjusted any desired length up to six inches in a few seconds and which when not necessary to be used can be adjusted back in the same time. I attain these objects by the mechanism illustrated in the accompanying drawing in which Figure 1, is a side view of the apparatus shown when in place and ready for action. Fig. 2, a side view of the split collar with peripheral lugs; Fig. 3, a transverse section showing an edge view of the device as placed in the wheel; Fig. 4, a detail view of the spiral spring, ratchet wheel, and ratchet frame; Fig. 5, a side view of the ratchet wheel and frame; Fig. 6, an end view of the ratchet block; Fig. 7, a top view of the ratchet wheel and frame; Fig. 8, a collar placed at the hub, one on each side of the split collar B to hold the same in place; Fig. 9, a mud lug and connecting rod.

Similar letters refer to similar parts throughout the several views.

The mud lug I is connected to the collar B, by the rod A, the threaded end of which carries a jam nut and is screwed into the mud lug.

"13, is a collar in two parts bolted together around the middle of the hub.

C is a bolt which p sses loosely through an unthreaded aperture in the parts D and E; the wheel F is fast on the bolt C, which is threaded into the member H; the innenend of the said bolt is surrounded by a spiral spring N, which acts as a cushion when the lug comes in contact with any hard substance.

D is a frame having an aperture in its outer end through which passes the bolt 0, and the inner ends of the said frame are attached to collar B.

E is the frame work of the ratchet as shown in Figs. 4, 5, 6, and 7.

F is a ratchet wheel located as shown in Fig. 1, and detailed in Figs. 5, 6, and 7; said ratchet wheel is fast on the bolt (3'.

G is a stationary wrought iron handle cast into the ratchet frame and can be pushed into action at Will.

H is a wrought iron block threaded to receive the bolt 0 at its inner end and having lugs at its outer ends, one at each'side to receive eye-bolts which are secured to the rim of the wheel as shown in Fig. 4-.

l is a mud lug adapted to pass through a perforation in the rim of the Wheel and can be adjusted to any desired length up to six inches.

J is a collar in two parts, to be applied at the hub at the side of the split collar B to hold the same in place.

K, K are eye bolts which pass through the rim of the wheel. Each eye bolt has a nut L on its outer end and an eye M, at its inner end to receive a lug of the -block,H.

When itis desired to extend the lugs, the lever G is caused to engage with the ratchet wheel F. The lever is now turned to the right whereby the bolt C- carrying the spiral spring N is screwed into the block H, and the split collar B is rotated to the left. The lugs are thus extended more or less through the rim. They may be drawn in by moving the lever in the opposite direction.

I claim: 7 5

In a traction-wheel the combination with a split collar having peripheral lugs and rotatively mounted on the hub, and connecting rods secured at their inner ends to the lugs and at their outer ends provided with jam-nuts and mud lugs adapted to pass through perforations in the rim of the wheel, of an apparatus to adjust the said mud lugs composed of a connecting frame attached to the split collar, a bolt mounted to slide in the loop of the frame and carrying a spiral spring between its head and the loop of the frame, and a block anchored to the rim, the said bolt being threaded into the block and operated by a ratchet lever attached to the bolt.

PAUL TOTEMS.
